Can’t find your Firefox web cache? Simple, type:

about:cache

into the address bar. This will give you your cache statistics. There are three sections:

• Memory cache - files in memory e.g. pages, css, images
• Disk cache - files on disk e.g. pages, css, images
• Offline cache - off lines files e.g. web site icons, downloaded java classes

Each section gives the memory currently in use and the maximum available. The the case of Disk and Offline cache the directory where those files are stored is given. If you want to fish a file from the cache, there’s an easy but awkward way of doing it. Each of the sections lets you list the contents, so to get a file from the Disk cache click the List Cache Entries link. This displays a page which contains all the elements in that cache. Search for the one you want and make a note of the file size. At the top of the page the Cache Directory is given. Open that directory and order the files by file size. Match the 2 file sizes! All the files in the cache will have cache file names like “4A62C7E5d01″ which are nice and easy for computers to read but useless for humans. When you think you have found the one you want, make a copy of it and rename it to it’s original file name. Voila - you’re done!

Plesk 8 uses Mailman to manage mail lists. The default Plesk configuration allows you to create a mail lists and add users to it, but it doesn’t switch it on! So here is what you do…

1. Log in to your Plesk server via ssh
2. Check the status of mailman, to see if it’s running:

   /etc/init.d/mailman status

3. If it is running, you can go to the configure your list section below.
4. If not, you will have to set the system to start it up.
5. Change to the boot start up directory:

   cd /etc/rc.d/rc3.d/

6. and check that it is set up to start it up on boot. Check that it is not already set up:

   ls -l | grep mailman

7. Start up scripts start with an ‘S’ and shutdown scripts start with a ‘K’. If there isn’t one to start up mailman you must create one:

   ln -s ../init.d/mailman S98mailman

8. You can alter that 98 number to change the start up order.
9. Next we need to start up the service:

   /etc/init.d/mailman start

10. You can check to make sure it is running with the status mailman command:

    /etc/init.d/mailman status

11. If it is running you can go to the configure your list
12. If not - you are on your own! Sorry…!
13. Now you can go into your Plesk admin pages, and start creating mail lists

I have almost finished the plesk mailman cheat sheet blog so I’ll post that when it’s ready.

This is one of my pet gripes. So I’m just going to explain why it’s such a problem. One of my roles here at BigSoft is to support various companies with their corporate network and the solutions that we have provided. Occasionally I get emails requesting support. I realise that not everyone is as computer literate as me and there are various shades of aptitudes. Choosing the Subject for an email is the important thing. Not only does it allow the email to be safely filed and easily retrieved, but it gets me thinking about your problem even before I have opened the email. I can judge how long it is going to take to respond - which makes me feel better. Although my emotional well being is not generally the issue, it does make me want to “go the extra mile” because I know they are actually interested in helping “us” solve the problem. I have kept all the email sent to me and all the email I have sent out for the last 5 years, so as you can imagine there is quite a lot! Digging out old emails is difficult at the best of times and so having an email Subject that describes the contents of the email is hugely valuable. So in an effort to make the general populace aware that some subjects just make my life unnecessarily complicated, I will list some of the more common Subjects that don’t really help or ingratiate yourself on the support person you are trying to engage. Help Hi Problem It’s broken Urgent problem Urgent help needed Some people write Urgent for almost everything. If a person writes this it means that they couldn’t be bothered to check the box which sends the email with a higher priority so it’s not actually that urgent. They have done whatever is easiest for them which shows that they are not really interested in solving the issue together - they just want you to do all the work so they can wash their hands of it. The subject is particular useful when using mailing lists or forums. You only need to spend a couple of seconds looking at some of the forums before you find the kinds of unhelpful subject titles I’m talking about. You will quickly see that the posts with a better subject have been read more times and as a consequence have more responses. I think that I have ranted enough. Needless to say that providing a good email subject that clearly states the intention of the email will get you better responses quicker.

Windows Remote Desktop allows users to use a Windows computer while not sitting in front of it. This is ideal for remote support. For security this feature is not switched on in the standard installation and so must be explicitly activated. In order to use Remote Desktop you must have a password set up on your machine. Below is a simple guide to switching this feature on:

1. Load File Explorer
2. Right click on My Computer select Properties
3. Click the Remote tab
4. Check Allow users to connect remotely to this computer
   On Windows 2008: Allow connections from computers running any version of Remote Desktop (less secure)
5. Click Ok

The Apache Tomcat instructions on this are here but they are both worse than useless and totally acurate. It starts we the sentence:

This section of the documentation applies to procrun 1.0, and is now obsolete

Great! Now what. There is no link to the document that supersedes it, nor what procrun is! Typical open source documentation! As with all these thinks you have to go reading old mail archives to find the answer. Buried about half way down an archive page on a generalist open source support web site is the answer. procrun is a thin (’C') executable program that can run java classes. An extension of procrun is prunsrv which also knows how to register services with windows. Now, here is the gem of information that lets everything make sense. The vital piece of information that would save everyone who reads the Apache Tomcat Windows documentation 2 hours of searching for…. wait for it….. Tomcat has compiled up prunsrv.exe with the instructions for starting and stopping Tomcat and renamed it to tomcat6.exe. If you find your tomcat6.exe executable, right click it and select Properties. Go to the Version tab and select Original File name is says “prunsrv.exe". The original Tomcat documentation is actually correct, the documentation page is obsolete because you should be reading the prunsrv.exe documentation. But good luck finding that - only kidding it’s here!.
